PHYSICAL DETAILS
The Noisetaker 701 employs the thermally regulated dual fan cooling system they introduced many years ago: An 80mm exhaust fan
on the rear of the PSU, and a 92mm intake on the bottom. It also includes a
manually adjustable fan speed dial that works in conjunction with the automatic
thermal regulation to bias the speed of the fans towards low noise or low temperatures.
One new feature of the Noisetaker V2 series is the introduction of what Enermax calls
a Ring Core. This consists of a gasket that fits around all of
the output wires as they exit the casing of the PSU that is designed to suppress
EMI. We do not have the equipment to test the actual effectiveness
of this feature.

Externally, the Noisetaker 2.0 revision looks identical to the earlier
version. The darker shade of blue indicates that our model has an active PFC.
A lighter blue version is available without active PFC.

There is a passive intake vent on the front that allows air to flow across
the internal components that are farthest from the fans. The "Ring Core"
that Enermax advertises can be seen around the cables as they exit the casing.

The internal PCB is neat and well laid out.

Loose spacing between the components means less airflow is needed for
adequate cooling.
Back exhaust fan at left; bottom intake fan on right. The larger intake fan
is rated for higher current, which means it moves more air than the exhaust fan. Why? Perhaps to
accommodate different pressure loads so that the inflow, after going through
the PSU (and some of it betting lost in back pressure), is equal to the exhaust
outflow.
Cables and Connectors
There are eight cable sets, as well as fan header that transmits a fan RPM
signal to the motherboard.

Aftermarket PCI-e adapter cable

It is in the number and type of cables that we expect to see the most
obvious differences between this Noisetaker V2 and the older version. In compliance with ATX12V 2.01, the main header now supports 24-pin
motherboards. Like the recently reviewed OCZ
ModStream, the header is convertible between 20 pins and 24 pins as
needed via an extra 4-pin plug that clips on the basic 20-pin connector.
Aside from the changes to the main ATX header, a PCI-Express connector
has been added, as well as two additional SATA power connectors. An additional
PCI-Express connector for SLI systems is available in the SLI model for $10 more. It has to be noted, however, that this PCI-e connector carries only 12V and ground lines; inexpensive adapters to convert two standard 4-pin Molex power connectors into a PCI-e connector are already available.
Flexible woven sleeves divide the cables into three bundles for improved management. This is a welcome improvement. The previous Noisetaker we reviewed had very stiff plastic
sleeves that made cable management ridiculously difficult.
